A few years ago, a large controversy was set in motion in the international scientific community about the possible existence of fossilized life forms in a Martian meteorite that crash-landed in Antarctica. The piece of rock, known as ALH 84001, was then believed by some to contain certain proof that life existed on ... |

While its twin Spirit is currently struggling to get out of Troy, the sandy trap that has been keeping it hostage since late April, Opportunity is having a field day studying a rock known as Marquette Island. On Sol 2070 (Nov. 19), the explorations robot used its rock abrasion tool's wire brush to investigate th... |

Scientists from the University of Arkansas (UA) have recently released a new report, claiming that the entire planet might have been formed out of meteoritic materials. They base their claims on the fact that the Earth's mantle exhibits the same set of isotopic signatures for magnesium as asteroids do, which wou... |

The last nine weeks have been very eventful for the Martian rover Opportunity, which has spent the first six of them looking at Block Island, a large meteorite it found on the surface of the Red Planet. After it looked at it from most possible angles – in a bid to provide its mission controllers with enough dat... |

One of the most famous asteroids was, for the scientific community, a space rock known as 2008 TC3, which was among the first to be scientifically observed as it entered the Earth's atmosphere, and burned down on descent. It was first spotted in 2008, and tracked until there was nothing left of it. Its surface a... |

Since 2006, the Nullarbor Desert in Western Australia has been the home of an experimental camera setup, designed and constructed by experts at the Imperial College London (ICL), in the UK, the Ondrejov Observatory, in the Czech Republic, and the Western Australian Museum. In a report published in the September 18th ... |

The meteorite that the Mars rover Opportunity discovered a few weeks ago is shedding more and more light on the past composition and state of the atmosphere on the planet. Following thorough investigations, experts have been able to infer that the gaseous mix was a lot thicker in the past than it is now. The conclusi... |

While shifting through the data beamed back by the rover Opportunity from the surface of the Red Planet, scientists at the Jet Propulsion Laboratory (JPL), in Pasadena, California, discovered a dark, oddly shaped rock sitting right in the path of the rover. According to preliminary analysis reports, it may be that th... |

Scientists from CSIRO Minerals Down Under Flagship, led by researcher Dr. Stephen Barnes, have finally been able to put a timescale on the intricate convection processes that take place deep inside our planet, when they have determined how platinum is generated throughout the core. The convection processes inside the... |

More than 3.6 million years ago, a massive meteorite struck the Siberian plains, creating an 11-mile-wide crater. Over the millennia, water flowed into the crater and thus Lake El'gygytgyn (or Lake E) was formed. Now, all those years later, scientists from the United States, Germany, the Russian Federation and A... |

The couple of meteorites was found in Antarctica during the 2007/2008 field season and constitutes a premiere for the scientific community – they are the first rocks from the solar system to have andesite on them, the heavy rock that forms the tectonic plates beneath our feet. Thus far, researchers believed tha... |

It is widely believed even today that most of the water on our planet along with other 'iron-loving' elements were brought to Earth during the last couple of hundred million years by asteroids, meteorites, comets and other such objects passing through the inner regions of the solar system. FSU's Depart... |

The model of planet formation in our solar system is currently very simple and easy to understand. All planets formed from the same materials inside the matter disk spinning around the Sun, thus spawning four most inner rocky planets and four gas giants. The raw material for the four inner planets is believed to have... |

Mining diamonds from Earth's crust is a messy business, especially if you consider that they are rather rare on the surface. Scientists predict that larger amounts of diamonds may be found in our planet's inner regions where they usually form; however, the enormous pressure inside the Earth and the great de... |

Asteroids, like most of the bodies in the solar system, have stable orbits around the Sun, as all of them have their origins in the debris left behind by the planet formation process. They are spread through all over the solar system, but are mostly concentrated in an area of space called the asteroid belt, situated ... |

Among the strategies regarding the possibility of preventing a catastrophic event, such as Earth colliding with a large asteroid or comet, we can find early detection, asteroid deflection or possibly the destruction of the object intersecting Earth's orbit. Some of these precautions could rise more problems than... |

Several movies have been made during the years depicting the potential catastrophic consequences of an asteroid or a comet intersecting Earth's orbit, and smashing onto its surface, or potential deflection strategies to avoid such a scenario.There are a lot of NEOs or Near Earth Objects, in the planet's orb... |
